Warehouse System Auto-Aligns Industrial Truck Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for aligning industrial trucks in warehouses require manual operator input for side orientation, which is inefficient and can lead to errors in positioning, especially when navigating between multiple pick positions.
Innovation Solution
A system where the warehouse administration system determines the side orientation and control commands are transmitted to the industrial truck to automatically align it for optimal access to pick positions, eliminating the need for manual operator input and enabling efficient navigation between multiple positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operator input is used for side orientation, then the operator can control the industrial truck, but the positioning precision deteriorates and errors occur
Solution Approach 1:
The industrial truck automatically determines its own side orientation based on the pick position, eliminating the need for manual operator input. The system self-adjusts by comparing the pick position with the current driving direction to automatically set the correct side orientation.
Solution Approach 2:
The system uses feedback from the pick position information and current driving direction to automatically adjust the side orientation. The warehouse administration system receives pick position data, calculates the appropriate side orientation, and transmits control commands to the industrial truck's control unit.
2Measurement precision
If automatic alignment is implemented, then positioning precision improves, but the device complexity increases
Solution Approach 1:
The warehouse administration system performs multiple functions: it manages pick positions, determines driving directions, calculates side orientations, and transmits control commands. The control unit on the industrial truck also handles multiple tasks including receiving commands, determining current direction, and adjusting orientation.
Solution Approach 2:
The warehouse administration system acts as an intermediary between the pick position information and the industrial truck control unit. It processes the information, calculates the appropriate side orientation, and transmits the control commands, simplifying the overall system architecture.
3Device complexity
If manual side orientation is performed, then the system remains simple, but the productivity decreases
Solution Approach 1:
The system determines the side orientation in advance based on the pick position before the industrial truck arrives at the picking location. This preliminary action allows the truck to be pre-positioned and pre-oriented, eliminating delays during the picking operation.
Solution Approach 2:
The automatic alignment system operates continuously, constantly monitoring the pick position and adjusting the side orientation as needed. This ensures that the industrial truck is always optimally positioned for picking operations, maintaining continuous productive action without manual intervention.

AI summary
A method for automatically aligning an industrial truck in a warehouse, the method comprising the steps of: confirming that a pick has been executed by an operator and issuing a pick signal indicative thereof; determining a pick position and a next pick position and issuing pick position signals indicative of each; determining a side orientation of the industrial truck relative to a shelf side of a shelf aisle of the warehouse by the warehouse administration system in response to at least one of the pick position signals; and issuing a control command signal to the industrial truck such that the side orientation is automatically assumed for at least one of the pick positions.
